[0035] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0036] This embodiment relates to a trailer hook assembly, which aims to improve the economy of maintenance and the aesthetics of the bumper 1 by optimizing its own structure.

[0037] In terms of overall structure, the trailer hook assembly includes a trailer hook 3 provided on the vehicle frame. The trailer hook 3 is detachably mounted on the vehicle frame and extends downward along the vertical direction of the vehicle. And from the front-to-back direction of the vehicle, the towing rope mounting point on the trailer hook 3 is located below the bumper 1 at the end of the vehicle. The bumper 1 is the bumper 1 of the vehicle at one end where the trailer hook 3 is provided.

[0038] The trailer hook assembly of the present embodiment can avoid providing a towing rope passage hole on the bumper 1 by positioning the towing rope installation point on the trailer hook 3 below the bumper 1. The use of the trailer hook 3 has no influence on the shape of the bumper 1, thereby ensuring the aesthetics of the bumper 1. At the same time, the trailer hook 3 can be detachably arranged, which can also facilitate the later maintenance and replacement of the trailer hook 3, thereby improving the maintenance economy.

[0039] Based on the above overall introduction, the structure of the trailer hook assembly in this embodiment is assembled on the frame as shown in FIG. Figures 1 to 3 As a preferred embodiment, a mounting bracket 201 for mounting the vehicle-mounted towing device 4 is provided on the vehicle frame, and the trailer hook 3 is mounted on the mounting bracket 201. Here, the trailer hook 3 and the vehicle-mounted towing device 4 share the mounting bracket 201, which can save the trouble of developing the mounting bracket 201 separately, improve the structural versatility, and help reduce the vehicle structure cost.

[0040] like Figure 2 and Figure 3 As shown in the figure, the mounting bracket 201 is connected to the frame longitudinal beam 2 in the vehicle frame, and the mounting bracket 201 is located at the bottom of the frame longitudinal beam 2, and the trailer hook 3 and the vehicle-mounted towing device 4 are installed at the bottom of the mounting bracket 201. Such an arrangement can facilitate the arrangement of the mounting bracket 201 on the frame longitudinal beam 2, and can also facilitate the installation operation of the trailer hook 3 and the vehicle-mounted towing device 4.

[0041] In specific implementation, the trailer hook 3 in this embodiment can be a rear trailer hook located at the rear end of the vehicle. In this case, the bumper 1 is a rear bumper, and the frame longitudinal beam 2 is a rear floor longitudinal beam. A rear anti-collision beam 5 is connected between the rear ends of the frame longitudinal beams 2, the vehicle-mounted towing device 4 is located at the front side of the rear anti-collision beam 5, and the bumper 1 is arranged at the rear side of the rear anti-collision beam 5 and is connected to the rear end of the frame longitudinal beam 2.

[0042] Preferably, the mounting bracket 201 in this embodiment may be box-shaped, and a cavity is formed between the mounting bracket 201 and the frame longitudinal beam 2. In this way, the box-shaped structure has a high structural strength, and the connection strength of the mounting bracket 201 on the frame longitudinal beam 2 can be improved. Of course, the structural form of the mounting bracket 201 can also be adaptively adjusted according to the use requirements.

[0043] To facilitate the removal of the trailer hook 3, the trailer hook 3 is installed on the mounting bracket 201 through a screw connection structure. The trailer hook 3 is installed through a screw connection structure, which is simple to install and can ensure the stability of the installation of the trailer hook 3. Further, in this embodiment, the trailer hook 3 and the vehicle-mounted towing device 4 share a screw connection structure. By making the trailer hook 3 and the vehicle-mounted towing device 4 share a screw connection structure, the number of installation points can be reduced, which helps to reduce the cost of the whole vehicle and improve the assembly efficiency of the whole vehicle.

[0044] In terms of detailed structure, Figure 3 , Figure 4 and Figure 6 As shown in the figure, the trailer hook 3 is bent and includes a first plate 301 arranged vertically and a second plate 302 arranged horizontally, and the second plate 302 is connected to the top of the first plate 301. The traction rope mounting point is located on the first plate 301, and the trailer hook 3 is installed on the frame through the second plate 302. Here, the trailer hook 3 is composed of the first plate 301 and the second plate 302, which is not only simple in structure, but also convenient for installation and arrangement on the frame.

[0045] In this embodiment, Figure 5 and Figure 6As shown, the traction rope installation point includes a traction rope installation hole 303 provided at the bottom end of the first plate body 301. The traction rope installation point adopts the installation hole, which has a simple structure, is easy to design and shape, and is also conducive to the installation of the traction rope. In addition, the traction rope installation hole 303 is arranged at the bottom end of the first plate body 301, which is also conducive to further reducing the height of the traction rope installation hole 303, ensuring that the traction rope installation hole 303 is located below the bumper 1.

[0046] like Figure 6 As shown in , the width of the first plate 301 is gradually reduced from top to bottom, so that the space occupied by the trailer hook 3 can be reduced, which is beneficial for the arrangement of the trailer hook 3 on the vehicle frame. As a structural example, the first plate 301 is roughly in the shape of a right triangle. Among them, the straight line portion corresponding to the top of the first plate 301 constitutes one right angle side of the right triangle, the straight line portion corresponding to one end of the first plate 301 disposed toward the bumper 1 constitutes the other right angle side of the right triangle, and the straight line portion inclined at the bottom of the first plate 301 constitutes the hypotenuse of the right triangle.

[0047] Here, the first plate 301 is set to be roughly in the shape of a right triangle, and the triangle has the characteristic of good stability, which can improve the use effect of the towing rope installation hole 303 on the first plate 301. At the same time, the position of the towing rope installation hole 303 is set as close to the bumper 1 as possible, which is conducive to improving the convenience of the trailer hook 3 in use. It should be noted that the first plate 301 can also be in other geometric shapes as long as it meets the use requirements.

[0048] As a preferred structural method, Figure 6 As shown in the figure, a reinforcing rib is provided between the first plate 301 and the second plate 302. The reinforcing rib here can improve the overall structural strength of the trailer hook 3. In specific implementation, two reinforcing ribs are arranged at intervals between the first plate 301 and the second plate 302. The width of the top of each reinforcing rib is the same as the width of the first plate 301, and the bottom of each reinforcing rib extends to the towing rope installation hole 303. Such a configuration is conducive to further improving the structural strength of the trailer hook 3. Of course, the number and specifications of the reinforcing ribs can also be adjusted according to the use requirements.

[0049] For the convenience of the following description, the reinforcing rib plate disposed close to the bumper 1 is referred to as the first reinforcing rib plate 304, and the other reinforcing rib plate is referred to as the second reinforcing rib plate 306. Furthermore, a weight-reducing hole 305 is provided on the first plate body 301 to facilitate the lightweight design of the trailer hook 3. Figure 6 As shown in , the weight-reducing holes 305 are respectively located on the left and right sides of the second reinforcing rib 306 . Such an arrangement can achieve the effect of weight reduction while ensuring the structural strength of the first plate body 301 .

[0050] To facilitate the connection of the vehicle-mounted towing device 4 on the mounting bracket 201, as shown in FIG. Figure 4 and Figure 5 As shown in the figure, the end of the vehicle-mounted towing device 4 has a mounting plate 6 for connecting to the mounting bracket 201. Preferably, the mounting plate 6 has a vertical portion 602 arranged vertically, and a transverse portion 601 connected to the top of the vertical portion 602 and arranged in the transverse direction. In the assembled state, the transverse portion 601 is located between the mounting bracket 201 and the second plate body 302, and the vertical portion 602 is located on the inner side of the first plate body 301.

[0051] In this embodiment, a plurality of screw connection structures are arranged at intervals along the length direction of the frame longitudinal beam 2 to ensure the connection stability among the vehicle-mounted towing device 4, the trailer hook 3 and the mounting bracket 201. Preferably, a screw connection structure is provided between the first reinforcing rib 304 and the second reinforcing rib 306, and two screw connection structures are provided at intervals on the front side of the second reinforcing rib 306.

[0052] The screw connection structure includes a bolt 7 which passes through the second plate 302, the transverse portion 601 and the mounting bracket 201 from bottom to top, and a screw sleeve which is arranged in the cavity of the mounting bracket 201 and is screwed to the bolt 7. The screw connection structure is simple, easy to install and disassemble, and has a good connection effect. Of course, the number and structure of the screw connection structure can also be adaptively adjusted according to the use requirements.

[0053] In addition, the trailer hook 3 in this embodiment is integrally cast, which can facilitate the preparation of the trailer hook 3, reduce the preparation cost of the trailer hook 3, and also ensure the structural strength of the trailer hook 3.

[0054] The trailer hook assembly of this embodiment adjusts the position of the towing rope installation hole 303 lower, which can ensure the structural strength and improve the reliability of the rear trailer hook 3. It also makes the installation and use of the towing rope not affect the shape of the bumper 1, thereby improving the aesthetics of the rear bumper 1. The towing hook 3 is installed by bolts 7, which has the advantages of convenient disassembly and replacement and good maintenance economy. In addition, by sharing the mounting bracket 201 with the vehicle-mounted towing device 4, there is no need to develop a separate mounting structure, and the structure has good versatility, which is conducive to reducing development costs.

[0055] In addition, the present embodiment also relates to a vehicle, in which the trailer hook assembly as described above is provided.

[0056] The vehicle of this embodiment is provided with the trailer hook assembly as described above, which helps to ensure the aesthetics of the bumper 1 and also facilitates the maintenance and replacement of the trailer hook 3.
